Janata Dal (United), heading the NDA government in Bihar, said that West Bengal under Mamata Banerjee is fast turning into a 'mini Pakistan' from where Biharis are being driven out by 'Rohingyas'.
The scathing criticism of the West Bengal government by JD(U) followed close on the heels of Mamata lauding her Bihar counterpart Nitish Kumar for deciding to contest assembly polls in four states separately.
"What is happening in West Bengal is a matter of grave concern. I have been saying this for long. I do not understand why she has thanked and commended our chief minister.
"May be she is happy that the JD(U) is contesting elections in four states on its own, not as a part of the NDA," JD(U) spokesman Ajay Alok told a news channel.
"But this gesture does not absolve her of her mistakes. She must act to prevent her state from degenerating into a mini-Pakistan," said the JD(U) spokesperson.
"Her thanksgiving cannot make us forget that Biharis are being assaulted in West Bengal and forced to leave the state," he added.
The JD(U), headed by Bihar Chief Minister Kumar as its national president, resolved Sunday to contest the assembly polls in Delhi, Jharkhand, Jammu and Kashmir and Haryana as part of its efforts to gain the status of a national party.
